A reminder on millisecond timing accuracy and potential replication failure in computer-based psychology experiments:...

Area of Science:

• Psychology
• Computer Science
• Research Methodology

Background:

• The field of psychology is experiencing a 'replication crisis,' leading to public and scientific scrutiny of study results.
• A significant portion of contemporary psychological research relies on computer-based experiments.
• Potential sources of error in computer-generated experiments, such as hardware and software, are under-examined.

Purpose of the Study:

• To highlight the potential impact of computer hardware and software on experimental timing accuracy in psychological studies.
• To address the role of millisecond timing errors in the failure of study replication.
• To emphasize the importance of precise timing for ensuring the reproducibility of psychological research.

Main Methods:

• This article is a conceptual review and reminder of existing issues.
• It examines the potential for millisecond timing errors introduced by computer systems used in experiments.
• It discusses the implications for the validity and replicability of psychological findings.

Main Results:

• Computer hardware and software can introduce millisecond timing errors into experimental procedures.
• These timing inaccuracies may be a contributing factor to the observed replication failures in psychological science.
• Current computer systems may not guarantee the millisecond timing precision required for robust replication.

Conclusions:

• Millisecond timing accuracy is a critical, yet often overlooked, factor in psychological research.
• Researchers must carefully consider and validate the timing precision of their computer-based experimental setups.
• Addressing potential timing errors is essential for improving the reliability and replicability of psychological studies.
